For unknown reasons, the bear lunged at 39-year-old Stephan Miller, a trainer at Randy Miller's Predators in Action, about 3 p.m. Tuesday and bit him in the neck, said sheriff's spokeswoman Cindy Beavers. Miller was pronunced dead at the scene.

Miller was a trainer at Predators in Action, a business whose website says the bear appeared in the recent Will Ferrell movie "Semi-Pro." The website also says it has "the best-trained grizzly bears in the business today."
